Guidelines for color images on color devices

• Just as important as the quality of the color images is the size of the images. Keep images small.
• Save photo-realistic images as JPEGs (they tend to compress the best).
• Make sure the images are the appropriate dimensions.
• Other than resizing the image, it is not necessary to alter photo-realistic images in any other way. The AvantGo Client does a good job of dithering the image to the 216-color palette.
• Convert line-art, such as maps and logos to the web-safe 216-color palette and save it as a GIF. Line art looks best when not dithered. For images that are not dithered, GIFs compress most clearly.
